Q: How does this work?
A: Cardboard on an Android phone requires version 4.1 or higher (look for the Cardboard icon in the Youtube Player). Cardboard on an iOS requires version 8.0 or higher. In iOS, you MUST download the Cardboard App! (https://itunes.apple.com/us/app/googl…)
Q: Does this work on the web?
A: Yes! You must be using Chrome. Control the camera using the arrow keys or your mouse!
